Heroes and Castles receives the biggest update yet, says App Advice. The update to the popular strategy game adds three more heroes, including a female assassin that can sneak in, kill, and sneak out. There is also a campaign that features a new environment with new enemies, though you must first beat the previous campaign before you are able to unlock this one. Additionally, there's a new versus and co-op map along with new ally units and upgrade levels for units and buildings.

• New hero added: Barbarian - Get in the fray and build your strength to untold levels!
• New hero added: Druid - Use the power of nature to support your allies and destroy the enemy!
• New co-op and versus map to battle on!
• New ally units! Destroy the enemy with a Dwarven Tank, hit long range targets with the Hunter, hold the line with armored Dwarven foot soldiers, or achieve victory with the powerful magic of 2 new Wizard classes!
